A wavelet analysis of solar mean magnetic field measurements

Solar mean magnetic field (SMMF) measurements from the Wilcox SolarObservatory and with SOHO/MDI are analyzed using continuous wavelettransforms, SMMF variability is found at a number of temporal scales.Detected SMMF variations with a 1-2 year period is considered to belinked to long-term variations in the internal rotation of the Sun.Intermediate SMMF oscillations with a period of 80-200 days are

Safety Concept and Design for Fire Resistance of Steel Structures

This paper is aimed at describing the principles on which are based the current concepts of fire engineering design of steel structures. The first part deals with the design methods for fire safety through the definition of heat exposure and structural models. The second part reviews the state of art in structural fire calculation methods, according to different levelsof assumption.

Traffic engineering of multiple spanning tree routing networks: the load balancing case

This paper deals with optimal load balancing in telecommunication networks based on multiple spanning tree routing. This is the case in switched Ethernet networks where the operator configures different routing spanning trees and assigns each demand VLAN to one of the spanning trees. We consider modeling and solving three load balancing objectives: (i) minimization of the average link load with a

Window Decoding of Braided Convolutional Codes

We consider a window decoding scheme for Braided Convolutional Codes (BCCs) based on the BCJR algorithm. We describe the principle of this decoding scheme and show that BCCs with window decoding exhibit excellent performance. The tradeoff between performance and decoding latency is examined and, to reduce decoding complexity, both uniform and nonuniform message passing schedules within the decodin

Systems Analysis of the Impacts of the Great East Japan Earthquake and Tsunami on Energy Supply System in Kamaishi-City

The Great East Japan earthquake and tsunami hit coastal cities in Iwate, Miyagi and Fukushima Prefectures of Tohoku Region devastating the energy supply system in the region. Electricity and fuel shortages caused severe problems in the city of Kamaishi varying from lack of mobility, communication, heating to reduced health conditions. This paper, aims to analyze the impacts of the earthquake and t

Synthesis and Photophysics of One Mononuclear Mn(III) and One Dinuclear Mn(III,III) Complex Covalently Linked to a Ruthenium(II) Tris(bipyridyl) Complex

The preparation of donor (D)-photosensitizer (S) arrays, consisting of a manganese complex as D and a ruthenium tris(bipyridyl) complex as S has been pursued. Two new ruthenium complexes containing coordinating sites for one (2a) and two manganese ions (3a) were prepared in order to provide models for the donor side of photosystem II in green plants. The manganese coordinating site consists of bri

Computing with Python

Description: Python® is a free open-source language and environment that has great potential in scientific computing. Computing with Python presents the programming language in close connection wit mathematical applications. The approach of the book is concept based rather than a systematic introduction to the language. It is written for a mathematical readership and is aimed at students with a ma
